🥣 How to Make Melted Leeks Pasta

Melting the Leeks

This recipe is pretty straightforward. First, sauté minced onions until soft and golden brown. Next, add sliced leeks and sauté for one more minute, just to give them some coloration.

Ingredients like leeks, pasta, onion, and butter

To prevent the leeks from sticking to the skillet, deglaze with water and cover. At this point, you want to cook the leeks for 20-25 minutes over low-medium heat until they melt and become very tender.

Adding the Pasta

Once the leeks are perfectly tender, bring a large pot of water to a boil and cook the pasta according to the package instructions. Drain, add to the melted leeks, and stir to coat.

It is that simple!

📔 Tips

  • Keep an eye on the leeks during cooking, as they tend to brown very quickly. If the leeks start to stick to the bottom of the skillet, add a couple of tablespoons of water.
  • For extra flavor, top with more ground black pepper and chopped parsley or cilantro. You could also add a generous sprinkle of vegan parmesan!
  • Consider doubling the recipe! This pasta dish saves pretty well, so if you want leftovers for the next day, we highly recommend making a double batch.
  • Feel free to use gluten-free pasta or rice noodles to make this recipe gluten-free.


Which type of pasta should I use?

Any long noodles like fettuccine, linguine, or spaghetti!

How to make leek pasta creamier?

While we don’t believe it’s needed at all, you can stir in half a cup of your favorite plant-based cream (cashew cream, for example) at the end of cooking for a richer and creamier consistency.

What to serve with this leek pasta?

It’s delicious on its own! For a more complete meal, you could serve it with baked or sautéed tofu or vegan steaks.

How long does this leek pasta keep?

It will keep for up to 3 days in the refrigerator. Reheat in a non-stick skillet over medium heat, and add 1-2 tablespoons of water if it starts to stick to the bottom of the pan.

*If you want more saucy noodles, save 1/4 cup of the pasta cooking water and add it at the end of cooking.

  1. Leeks always look so beautiful, but I’ve never quite known how to use them except in a soup, maybe an omlet. This looks great. Thank you.
